Here is Source code of a commonly asked C++ job interview question: Fibonacci series


int main()
//define first two fibonacci series numbers.
int fib1 = 0;
int fib2 = 1;

//declare the variable to store the next number of fibonacci series
int fib3;

//declare the variable to store how many numbers to be printed. Default is 2.
int numbers = 2;

//the counter to keep track how many numbers are printed.
int counter = 2;

//Ask user how many numbers of the fibonacci series need to be printed.
std::cout << "How many Fibonacci number you need ? : " ; //Store the number. std::cin >> numbers;

//If number entered is less than 3, exit the program.
if (numbers < 3) return 0; //Print the first two element. std::cout << fib1 << "\t" << fib2; //do-while loop to calculate the new element of the series and printing the same. do { counter++; fib3 = fib1 + fib2; std::cout << "\t" << fib3; fib1 = fib2; fib2 = fib3; } while (counter <= numbers); std::cout << std::endl; system("pause"); return 0; }

About caustic

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at
